Beit known tbatLIsAAc Pannen, of Vineland, in :the county of Cumberland, and Stats of New Jersey,

i have invented'a new and improved Concrete-Brick Machine; and I do hereby declare that the following is afull,

clear, and exact description thereof, which willcna'blc others skilled in the art to make and use the same, reference being had-to the accompanying drawings,.forn1ing part ot' this specification, in which- Figure 1 represents a side elevation, partly in section, of my improved brick-machine.'

Figure 2 is a vertical longitudinal section of the same. Figure 3 is a detail transverse section ofthesame, the plane ofsect'ion beingindicated by theline. x nhg. 2. Similar letters of reference indicate, like parts. I l

f This invention relates to a new machine for pressing andforming concrete stones'i'or building purposes, in a separate press, which is so constructed that it can bereasily handled, and that the ready-pressed concrete can be easily removed from it. i

` -A represents a horizontal .frameof rectangular or other suitableshape, and made ofvsuitable material. It is the bed o r support for the other portions Vof the machine. ,B Bare two-vertical plates, arranged on either side of the'frarce A, and projecting upward from the same. Their upper ends are connected by a horizontal plate, C, whichis as .longland wide as the concreteis to be. is a rectangular box, of such dimensions as to lit close around the plate C; it hasn'elither top nor bottom. In its inside isa core, E, which is a block of the same height as Vthe box D, and which is secured to the same by meansot' braces, ava, vat its under side, as: shown. The box D having the core E, vis fitted around the plate (l y'and plates B, in' such a'manner that it can easily slide up and down yon lthe same. It is,'atl its under side, prvovided with a. vertical projecting pin, b, the 'lower endof which is" pivoted Vtoa lever, F. The lever Flins its fulcrum on 'a chain, Gasthat is suspended from a small yoke, H, which is fitted Vupon the framep, .as shown. By means of'tlhis lever F, th'e'box D and core can be raised and lowered at will. When loweredthe edge ofthe end-pieces of thebox will rest upon shoulders, e,`which are formed o'u the uprightsBf The surface of the plate C will be hush with the upper edges of box and core, as .in iig. 2. VWhen thebox is raised, asV in fig. 1, the plate Cfwill form -the bottomof thebox, the- `latter being upheld by springs del, Awhich are formed on the sides of the uprights B, as shown. It must here be remarked that the plate CLis slotted, tojenable it to it around the core E. -I is a horizontal shaft, having its bearings in the frame A,'directly below the pin 6, and connected at one end with'a long crank or lever, J, 4

A chain or rope,'K,connects the lowerend of they pin biwith the shaft I, in such a. mannerth'at, by means of the lever J, the chain can b'ewound around the shaft Land the boxDbe lowered. A great deal of power is gained by this arrangement.' VWhei the box is raised, thecement, die., for forming the concrete, is put intoit.

L is a sliding cover, which has -grooved sides, e @which fit around strips,ff, that are secured to thesides of the box, near its upper edge, as sh'own.` Theser strips-f, and grooves e, prevent the cover L from being raised from the box. VWhen the cementi's in thebo'x, and the cover L drawn over .the same, the'box is, drawn down by means ofthe lever J, and the cement is compressed between-'the plates C and L. When suciently pressed, the slide L is drawntp one side, when it will rest upon a plate, M, Vthat is provided for the purpose, andasheet metal box, N, which is as wide and long asthe inside of the box D, and as high as the concrete' when pressed, and whichhas a core, to correspond with .the core E, is placed bottom-upnpou the box D, and then lthe latter is lowered, by means of the lever F, until kthe bottom, C, is usb with the top of the box D, as in hg..2, when the concrete will have been' transferred to the, inside of the box N, `as is indicated by red lines in 'g. 2. O -s' a table or platform, which is pi-voted-between braces, y g, that project from that side of the box D which-is i opposite to lthat onV which the plate M is arranged. This platform O is ush with the top'of box D, and the' box N can be drawn towards andupon.' it.l When the'box- N stands upen theV plate O, the latter can be turned l on its pivots, so that the vbox- N'may be turned 'bottom-down. The -plate O is acting as a cover'for the boxN while th same is beingturned, thereby preventing the'concrete, or parts of it, from falling out. The concrete is then taken, -in the box N, tothe drying-room, or to any othersuitable place. Y When dried, it can be easily removed from the box NL Y ThecoreEforms a Vslot in the `centrerof the concrete, as shown (inhg. 4, whichisav top viewof a Aconcrete formed in my machine,) which slot serves to facilitate and hasten'the drying `of the matter,` and which will also serve to form"excellentvventilatingfues in buildings.

-What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of the levers F land J, when the same are connected with the sliding box D, in the manner set forth.

2. The sliding box D, in combination with the. uprights B, plate C, pin b, lever F, chain K, shaft I, :mdlever J, all made and operating substantially as and for the-purpose herein shown and described.

3. The box D, i'vhen provided with a core, E, in combination with the sliding plate L, that lies grooves, e and fits over strips,f, as set forth. l

4. The hinged plntfornl O, in combination with the box N and box D, all made and operating snbstantnlly asand for .the purpose described. l

5. The springs d, when arranged as set forth, for the purpose of keeping the box D np, as set forth.
